Abstract

Background/Objectives: IOT is the network of physical objects that are incorporated with electronics, software, sensors and connectivity to enable objects to exchange data with the manufacturer/operator/other devices connected. The objective of this paper is to monitor and control the smart home system from anywhere around the world. Methods/Statistical Analysis: With more and more applications of IOT in various domain, it also steps into smart homes. Smart home system is one of the most essential application using IOT. In this paper the ZigBee technology is used for the networking of smart things i.e., the objects that are to be monitored and controlled. The smart home system consists of various sensors like temperature sensor, motion sensor, air flow sensor, ultrasound sensor and actuators for controlling the smart home system. These sensors are connected to the ZigBee modules which are interfaced with Arduino boards. This setup forms the network with the WiFi modem through which the monitored data’s are entered into the internet server. An android application is established with which the user can monitor his/her home anywhere in the world. The performance of IEEE 802.15.4 (ZigBee) is also analyzed, which includes the parameters such as the SNR and BER. This is in dubiously going to be a mile stone for the next generation since it moves the field forward by automation of home. Findings: The performance analysis of SNR and BER was carried out it was inferred that as SNR increases the BER decreases with respect to the number of bits transmitted. Application/Improvements: Android application can be developed to monitor and control the smart home system.
